Hi Ilya the exact same applications run on the system, there is no way that class is missing.
by the way i have run some more tests; with a new clean ignite-cluster setup we did not get the errors and systems runs smoothly. only difference here is the upgrade proccess, there should be a problem with the data migration over upgrade proccess. ----- İbrahim Halil Altun Senior Software Engineer @ Segmentify -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
